Robert Jördens e31ee1f0b3 firmware/i2c: rewrite I2C implementation 
* Never drive SDL or SDA high. They are specified to be open
  collector/drain and pulled up by resistive pullups. Driving
  high fails miserably in a multi-master topology (e.g. with
  a USB I2C interface). It would only ever be implemented to
  speed up the bus actively but that's tricky and completely
  unnecessary here.
* Make the handover states between the I2C protocol phases (start, stop,
  restart, write, read) well defined. Add comments stressing those
  pre/postconditions.
* Add checks for SDA arbitration failures and stuck SCL.
* Remove wrong, misleading or redundant comments.

David Nadlinger 3f0cf6e683 runtime: Stop kernel CPU before restarting comms CPU on panic 
Before, the system would enter a boot loop when a panic occurred
while the kernel CPU was active (and panic_reset == 1), as
kernel::start() for the startup kernel would panic.

This seemed like a good idea then, but it introduces complexity, corner cases, and additional testing difficulties.

Now Sayma works fine with Kasli as a master, which is simpler.

Sebastien Bourdeauducq ec230d6560 sayma: move SYSREF DDMTD to the RTM 
Put RTM Si5324 into bypass mode before running.

Sebastien Bourdeauducq cb04230f86 sayma: SYSREF setup/hold validation demonstration

requires a DRTIO transceiver due to the Ultrascale TPWS bug.
